bzr itself has never supported them. We've talked about it, and as long
as you implement a cache, so that you don't have to read the content of
every file, it could still perform well. (If a file matches your mtime
cache, then you can assume the file-id hasn't changed as well).

But for now, we don't support it. And it isn't in the roadmap to do so.
